The Kayopo, an indiginous tribe in the Brazilian rainforest, have lost over 200,000 acres of their preserve to the illegal gold mining encouraged by Jair Bolsonnaro. On this week’s Kicker, Jon Lee Anderson, a staff writer at the New Yorker, tells Kyle Pope, editor and publisher of CJR, how he embedded with the Kayopo, who had no regular contact with the outside world until the 1950s. Anderson describes the tactics used by gold prospectors to sow discord among the Kayopo, and tells of the heartbreak some feel as they accept work that they know will destroy the environment.
